Title: Multi-track tape recorder
Inventor: TANAKA MASATO
IPC: G11B5/09
Filed: 1981-10-31
Abstract: PURPOSE:To eliminate the tracking, by synthesizing the outputs of plural reproduction heads which are distributed in a range larger than the width direction where signals are recorded on plural tracks and with a pitch narrower than the track. CONSTITUTION:Plural reproduction heads HP1-HPm which are more than the number of tracks are provided in a range larger than the width of plural tracks and with a smaller pitch than that of the track. The output of a reproduction head Hi is connected to a reproducing circuit 3i via a reproducing ampifier 2i including a comparator for shaping of waveform. The circuit 3i is provided with a bit clock reproducing circuit, a channel decoder, an error checker, etc. and connected to a time base collector (TBC)5 via a data/block address queuing register circuit 4i. The 1-channel audio PCM signal is delivered from the TBC5 and undergoes a D/A conversion after an error correction carried out through a decoder 6 to be delivered in the form of an analog output 8. In such way, the tracking is eliminated to ensure the correct reproduction.

Title: Zoom lens
Inventor: RII ROI ESUTERU
IPC: G02B15/20
Filed: 1988-07-13
Abstract: PURPOSE: To keep a lens out of the visual field of a finder to minimize the parallax of the finder by making the total length from the apex of the front surface of a front lens to a focal surface shorter than 1.8Fs (Fs is a short focal length) when a short focal length is set, and making it shorter than FL (FL is a long focal length) when a long focal length is set. CONSTITUTION: In the lens, there are provided with a front negative lens structure body, a positive lens structure body, a positive cemented compound lens structure body, a rear negative lens structure body 33 consisting of three lenses. Four lens structure bodies which can be moved in the axial direction to change the focal length at least in a range of 2.5:1, and a diaphragm provided with the first positive lens structure body are provided. The total length from the apex of a front surface R1 of the front lens A to the focal surface is made shorter than 1.8Fs when the short focal length is set and is made shorter than FL at the time of setting the long focal length. Thus, such small-sized zoom lens is obtained that a part of the front end doesn't interfere with the visual field of the finder even when the finder is arranged closely to an image pickup lens for the purpose of reducing the parallax.

Title: Unauthorized use preventing method for pager and pager having unauthorized use preventing function
Inventor: IIZUKA KAZUAKI
IPC: G06F21/62
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To prevent unauthorized use of a pager by illegal copying of an ID code by comparing the code value calculated from an identification code with a comparison code stored in a volatile memory and discontinuing the subsequent operation if no matching is secured between these codes. SOLUTION: A CPU 2 receives an ID code, the system information, the frequency data and an identification code of every contractor from a code programmer 9 and stores the received data in a prescribed area of an EEPROM 7. Then the CPU 2 calculates a comparison code B that is obtained by a prescribed calculation method from the received identification code and stores the code B in a prescribed area of an SRAM 6. When the power supply of the pager device 10 is applied or a system is started again, the device 10 reads an identification code A out of the EEPROM 7 and then calculates a calculation code C in the calculating method of the code B. If the code C is not coincident with the code B of the SRAM 6, it's decided that the EEPROM 7 is illegally copied Then the original operation of the device 10 is discontinued.

Abstract: PURPOSE:To convey a truck by upper and lower conveying paths in a conveying device in which the truck circulates on the upper and lower conveying paths by dislocating sprockets of truck-conveying chains provided on both sides of the conveying path by an amount of the distance between front and rear wheels of the truck in a front to rear direction, and guiding the truck so that the oscillation can be prevented when it turns. CONSTITUTION:When a conveying truck 1 is lowered from an upper side conveying path 10 to a lower side conveying path 11, wheels 4,7 on a diagonal line of the truck 1 connected to chains 21,22 are lowered simultaneously by sprockets 12, 14 dislocated in a front to rear direction. When the conveying truck is lifted from the lower side conveying path 11 to the upper side conveying path 10, the wheels are lifted simultaneously in the same manner by sprockets 13, 15. Thus, the truck 1 does not turn over to be shifted with its position kept as it is. Wheels 5,6 on an other diagonal line are guided by first guide members 32, 31 and second guide members 35, 36, and shifted without causing oscillation. In this constitution, the upper and lower travelling paths can be used together as the conveying paths.

Abstract: PROBLEM TO BE SOLVED: To obtain the efficient moving image monitor equipment with high reliability by providing an image nonsensing section lacking at least one image sensing element to at least one part of an image sensing element arrangement section being an assembly of image sensing elements. SOLUTION: An image pickup object 1 caught as a 1st image pickup object image 14 is partly caught by an image nonsensing section 12. On the other hand, the image pickup object 1 caught as a 2nd image pickup object image 15 is partly caught by an image nonsensing section 13 and the caught part is opposite to that caught by the image nonsensing section 12. Thus, the part of the image pickup object 1 caught by the image nonsensing section 12 resulting in being unclear is caught as the 2nd image pickup object image 15. On the other hand, the part of the image pickup object 1 caught by the image nonsensing section 13 resulting in being unclear is caught as the 1st image pickup object image 14.  Thus, the image signal of the 1st image pickup object image 14 and the image signal of the 2nd image pickup object image 15 are processed totally to catch the entire image of the image pickup object 1 at all times.

Title: Forming method for cvd film
Inventor: MATSUKI TOMOYOSHI
IPC: C23C16/50
Filed: 1991-07-17
Abstract: PURPOSE:To form a CVD film of desired quality with constant thickness even if an insulating film is deposited on a rear surface of a silicon wafer by switching a frequency of a high frequency signal among a plurality of stages to be controlled when the signal is applied to a plasma CVD device to form the CVD film. CONSTITUTION:When an insulating film 3 is deposited on a rear surface of a silicon wafer 2, an impedance of a holder depends upon a capacity of the insulating film and a frequency of an RF wave. A CVD film formed on the wafer 2 is necessarily a film having high quality and high denseness on a part in contact with the wafer 2, but a part which is not in contact with the wafer is not important and may hence be of low quality. The frequency of the RF wave is set to 450kHz for a relatively short time, and a CVD film 6 is formed thinly. Then, the frequency is switched, set to 1MHz for a relatively long time, and a CVD film 7 is formed thickly on the film 6. Thus, the film 6 becomes a high quality and dense, and the film 7 becomes a low quality and porous.

Filed: 1990-07-05
Abstract: PURPOSE:To ensure complete continuity of a horizontal synchronizing signal and to effectively suppress occurrence of 'vertical flicker due to duplicate display' and 'deterioration in vertical resolution due to interpolation' by controlling a delay of a delay line of a variable length type synchronously with the field reproduction period. CONSTITUTION:A difference between a minimum delay and a maximum delay of a variable delay lien 13 is selected to be a time equivalent to 0.5 line (0.5H) and the delay is controlled by an oscillating frequency of a delay clock signal inputted from an oscillation circuit 17. The oscillation circuit 17 controls the oscillating frequency of the clock signal so that a delay in the variable delay line 13 is increased smoothly or at a small step from the start to the end of a field reproduction period. Thus, a synchronizing signal having been delayed by just 0.5H just before a pulse generator PG is compensated just after the PG.
